To all whom it may concern:

Be it known that I, DAviDC.- A.v BoswoRTpH, a Acitizen of :theUnitedStates, and a resident of New York city, borough of Brooklyn, in thecounty of Kings andv State of New York, have made yand invented vcertainnew and usefulY Improvements in Phonograph Attachments, of which thefolllowing is la specification.

My invention relates to a winding mecha-- Y nismfor honographs, whichmaybe easily and readily attached to a phonograph regardless of its sizeor particular make, and will,'efiiciently and vquickly rewind thephonograph'motor when actuated by aY Adirect pull upon a iiexible memberor ta4 e.

I am aware ythat it'has hereto orexbeen proposed' to provide a rewindingmechanism for a Aphonograph which is substituted Yfor the ordinary crankhandle and is'operated by a direct pul'lupo'n aflexible member or tape.VIn all such devices, however, as heretofore constructechitv hasbeenlnecessaryY to rigidlysecure them to the cabinet of the`phonographand in so doingthey becornea permanent part thereof. tachmentVof the winding mechanism to the phonograph `"requires theV yuseV ofholding `screws or other attaching means, which tends to mar and injurethe cabinet. Furthergthe attachmenty of thawinding device has heretoforerequired the use of special tools and V'the employment of considerableskill and 4in 4addition has pre-y sented an unsightly appearance, 'beingin discord withv the lregular and symmetrical lines of the usualphonograph cabinet.

' It is accordingly an'- objectl of my inven-v tion to providearewinding mechanism, which may beeasily and quickly secured `toaphonograph, does notv comprehend the use of holding -screws. or similarattaching means, and accordingly does not involve the AmslLrri-ngio'rinjuring of the cabinet. Further the rewinding ymechanism is yof simpleYand neat appearance, occupying but little space, and *conforming tothesymmetjri'cal lines of the ordinary phonograph cabinet.

Vgraph Winder having Athe aforementioned i'characteristics, and which,in` addition, is

A further object is to provide a phono simple'in construction, may beYreadily and economically Lmanufactured, and vcapable of efficiently:'erforming, the service* for which it is inten ed'.m Ciurtherv the.windingmecha- This' atf nism embodies a minimum number of parts,softhat thev entire device will be rugged and durable in service. f Y

With the foregoing and other objects in view, whichY will Vappear as thedescription proceeds, my invention resides in the novel phonographrewinding mechanism, as vhere- Y equipped with my improved iewinding`attachment;

Referring specifically` to the several views wherein similar. referencelnumerals designate corresponding parts throughout,

my improved phonograph rewinding attachment is composed of a maincircular casing 10, which isopen at the'front eX- tremity and isprovided with a cover 11. Housed withinthe casing 10 is a drum12, tolwhich is,-rigidly'sec'uredy a vbushing 13.

The rear wall 14 ofthe casing is provided with an opening 15 therein,which rotatably receives the bushing 13 therethrough. A p ortionofthedrum `12 is cut away as at 16, and receives a ratchet wheel l1'?therein.-

A pawl. 18" is .pivotally secured `to the drum A1.2, by .the pin orotherattaching means 19,

VVthe action of the'` pawlz-and ratchet'wheel being to yallowthe drum121:0 rotateV freely in )one direction independent ofthe ratchetv n sionspring 21.

wheel, but to forciblyl drive themratchet wheel when rotatingintheopposite direc effecting a rotatable joint therewith is theishould'itbe so desired.

A washer or ring 28 is fixedly secured tol winding shaft 23,A the oneextremity of which, as illustrated in Fig. 1, is `secured to,

Vso as to positively drive, the phonograph motorM. rThe winding shaft 23projects through the opening in the side wall 24 of the phonographcabinet and is provided adjacent its outer extremity with the rigidlyattached' ratchet wheel 17. Extending inwardly from the center of thecover of the casing is the pivot.-` pin 25, which forms a bearingsupport for the front extremity of the winding shaft 23, the latter'being pro vided with an opening 26 in' which the bearing pin 25 fits andeffects a rotatable june-- ture. Y v The winding shaft 23 i is providedwith the outstanding projections 27, thus affording vmeans for manuallyturning 'the winding shaft in a reversed direction so that it maybe'disconn'ected from the phonograph motor M, and the attachment removedthe bushing 13, and holds it and the drum to lwhich the same isconnected in place during such time as the cover 11 is-removed. The;winding drum'is preferably provided with a groove 29, which receives aflexible member ortape 30 therein, the same being composed of a metalstrip 31, surrounded bya vcloth covering 32. The protruding extremity ofthe flexible tape is provided with the handle 33. Suitable rollers 3ftare situated adjacent the opening '35 vin the casing. and through ,whichthe kflexible tape extends, thus preventing undue wear upon thetape.

4With the parts as thus arranged whenthe handle 33 is firmly grasped andmoved outwardly, it'causes therapid rotation of the drum' 12,' which isimparted tothe winding shaft'23 by means of the pawl18 and ratchet wheel17, thus causing the Winding or. rewinding of the phonograph motor. Atthe 'same time, the spring 21 is wound or energized I-due to-vtherelative rotation of the ydrum and thelcasing `10. The'ca-sing ispre- -vvented -from:rotating'bythe action ofthe j ltapey bearing uponthe vroller 34. After the tape has been unwound, the handle 33 is"-move'd inwardly, allowing "the"l drum l 12.' to

rapidly rewind the tape thereon, due tothe action of the spring 21; theeasing remain-V ing stationary during this operation due to thepresenceof the tape bearing upon the roller'34l. In fact itehas beenfound that should the handle be suddenly releasedafter having been drawnout to its furthest point,A

the weight of the handle will be sufficient to maintain the tape tautduring this rewinding and thus hold theV casing against rotation and infact should the rotation of the casing take place, rather than thereverse Y turning of the drum, the same effect vwill be had as therotation of the casing would re- 'i wind the tape upon Vthe drum and inso doing return the handle to its'original and retracted position. VThecasing, being supported solely by the shaft 23 and the shaft beingadapted to rotate with respect to the casing, is allowed to assume aposition wherein theV flexible member when pulled will assume a straightlinev and 'tangential tok the druml upon which the flexible member'iswound, so that the entire pull willbe directly transmitted to the drumwith the least possible friction andregardless Vof the particulardirection in which the handle yis pulled..

In order to make the attachment of unif versal use, several ofthewinding.'Y shafts with the ratchet wheels thereon are provided and areof different lengths 4and pro# vided with different end connections'forthe first ascertained and then a shaft of proper length and constructionprovided and sevmotor M, kso that in supplying a'icustomer with one ofmyv improved winding `atta'chf ments the size and style of phonograph iscured in place flrstvremoving thecove'r 11 and inserting the winding`shaft through the bushing 13, and then replacing the coversubstantially as shown in "the drawings, a

.reversed procedure being used'when for'any reason it is ldesired toremove 'the winding attachment from a phonograph.` Q j The somewhatmodified form of construction illustrated in Figs. 5, 6, and 7 ismodilied only with regard" tothe construction of the several parts andoperates in a precisely' i similar manner, to that above outlined.Referring' to the drawings in question, the drum 50'is preferably formedof stamped metal and composed ofv the1web,"rim and flange 51, anda'second flange piece l52,'is

held to 51 by the ears 53, thus forming alight `and'economical wheel ordrum. Securedto the web is the bushing 54, which is rotatably `mountedupon av sleeve 55, they latter "being in turnv rotatablyj mounted `vatits'front exf `tremity by the bearing 56,' and at its .rear

extremity by the opening '57 in the vrear wall of the casing 58.VRigidly* secured tothe sleeve 55v and resting against the web ofthe drum51 vis theratchet wheel 59,which" Vthrough theaetion of the-pawl 60fisadapted to positively rotate the sleeve 55 upon the ro-y iso tation ofthe drum 51 in one direction, the reverse rotation of the' drum takingplace independent of the sleeve. The bushing 54 is extended so as tobear against the rearl wall of the casing 58, which feature togetherwith the action of the ratchet wheel bearing against the web of the drumand the reception of the sleeve 55 within the bearing 56, holds theseveral parts against longitudinal shifting.

In order that the rotation of the sleeve will effect the rotation of thewinding shaft of the phonograph and in order that the said winding shaftmay be of the vproper length and construction, so as to fit' a certainVor given type of phonograph, I have preferably providedthe sleeve -a-tits upper extremity with the reduced squared aperture 61, and inaddition have provided the main aperture 62 of the sleeve with asemi-circularl groove 63, in which is contained a wire ring 64. Thewinding shaft 65 is provided at its outer extremity with the squared end66 and with the semi-circular grooves V67 adjacentV the same. Thus whenit is desired to supply a customer with my improved winding attachment,a Vwinding shaft of the proper length and construction for thephonograph in question is selected, the original winding handle of thephonograph removed and the winding shaft 65 secured in its place, theextremity of the Winding shaft protruding through the side of thephonograph cabinet substantially as shown in Fig. 5. The casingcontaining the various parts therein as previously described, isforcibly moved upon the winding shaft until the squared end of the shaftreposes in the squared extremity of the sleeve, the wire ring inthesleeve engaging one of the grooves in the winding shaft and holding thecasing securely in adjusted position. A flexible tape 68 having a handle69 is provided and enga-ges the drum as previously described. A torsionspring 70y is secured to the bushing 54 and to the casing 58 andprovides for the retraction of the tape or flexible member after it hasbeen forcibly drawn out during the winding operation of the phonograph.A' piece of felt or :other suitable material *71,v is carried by tion,what I claim is l. Av phonograph rewinding attachment comprising a shaftadapted to engage a phonograph motor, a casing engagingsaid shaft andsolely supported thereby and adapted to turn with respect to said shaftand with respect to said phonograph, a flexible member, and means housedwithin said casing engaging said shaft and said casing and engaged bysaid flexible member and adapted to rotate said shaft as said flexiblemember is pulled outwardly for the rewinding of said phonograph motor,and to cause the free retraction of said flexible member, said means andthe mounting. of said casing adapted to allow the casing to. turn withrespect to' the phonograph and to accommodate itself to the direction ofpull upon the flexible member.
